Assessment of nitrous oxide emissions from agricultural systems in Thailand and low carbon measures

Abstract

The goal of this article is to assess the current emissions of nitrous oxide (N2O) from the Thai agricultural system and its regional distribution characteristics. The nitrous oxide emissions from crop cultivation and manure management processes in each region of the country were evaluated using the recommended methodology of the United Nations Intergovernmental Panel on Climate Change (IPCC), together with official statistics. In terms of spatial distribution, nitrous oxide emissions differed significantly among regions, with the largest emissions in the central region, followed by the northern and northeastern regions and the smallest emissions in the southern region. Given the characteristics of the agricultural and livestock industries in Thailand, it is recommended to improve field management measures through a reasonable application of nitrogen and better irrigation models. To reduce nitrous oxide emissions by appropriately adjusting the farming structure, improving the storage environment and improving manure treatment, and explore new low-carbon farming models such as combined farming and recycling to achieve nitrous oxide emission reduction and scientific control.
